Study characterizes 300-million-year-old tropical forest preserved in volcano ash
(PhysOrg.com) -- Pompeii-like, a 300-million-year-old tropical forest was preserved in ash when a volcano erupted in what is today northern China. A new study by University of Pennsylvania paleobotanist Hermann ...
Coal yields plenty of graphene quantum dots
The prospect of turning coal into fluorescent particles may sound too good to be true, but the possibility exists, thanks to scientists at Rice University.
Researchers find smoking gun of world's biggest extinction
About 250 million years about 95 per cent of life was wiped out in the sea and 70 per cent on land. Researchers at the University of Calgary believe they have discovered evidence to support massive volcanic ...
To clean up the mine, let Ascomycete fungus reproduce
Harvard-led researchers have discovered that an Ascomycete fungus that is common in polluted water produces environmentally important minerals during asexual reproduction.
Study on fungi helps explain coal formation and may advance future biofuels production
A new study--which includes the first large-scale comparison of fungi that cause rot decay--suggests that the evolution of a type of fungi known as white rot may have brought an end to a 60-million-year-long ...
Alien world is blacker than coal
(PhysOrg.com) -- Astronomers have discovered the darkest known exoplanet - a distant, Jupiter-sized gas giant known as TrES-2b. Their measurements show that TrES-2b reflects less than one percent of the sunlight ...
Switching from coal to natural gas would do little for global climate, study indicates
Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change. The study appears ...
New thermocell could harvest 'waste heat'
(Phys.org) —Harvesting waste heat from power stations and even vehicle exhaust pipes could soon provide a valuable supply of electricity.
Report: Direct removal of carbon dioxide from air likely not viable
Technologies for removing carbon dioxide from the atmosphere are unlikely to offer an economically feasible way to slow human-driven climate change for several decades, according to a report issued by the American Physical ...
Mercury levels in Pacific fish likely to rise in coming decades, study reports
University of Michigan researchers and their University of Hawaii colleagues say they've solved the longstanding mystery of how mercury gets into open-ocean fish, and their findings suggest that levels of ...
Skilled hunters 300,000 years ago
Finds from early stone age site in north-central Germany show that human ingenuity is nothing new – and was probably shared by now-extinct species of humans.
New coal technology harnesses energy without burning, nears pilot-scale development
A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing ...
Reports from "Humans 2 Mars Summit" suggest dust may prevent human settlement of Mars
Africa to spew half world's particle pollution by 2030, study says
With its exploding urban population burning ever more coal and wood, Africa could contribute as much as 55 percent of the world's particle pollutants by 2030, a study said Tuesday.
